Process Equipment and Plant Design In the allocated cap area, bubble caps are generally arranged on equilateral triangular pitch. Number of caps fixed on a plate is with a Neither A nor B Cap pitch of 1.3-2 times the cap diameter Either A or B Clearance of 25-75 mm Neither A nor B Cap pitch of 1.3-2 times the cap diameter Either A or B Clearance of 25-75 mm ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Pressure drop due to pipe fittings can be estimated by the equation, ΔP/p = 4f.Le/D.V2/2gc, where, Le = equivalent length of straight pipeline which will incur the same frictional loss as the fitting and D = diameter of the fitting. The value of Le/D (dimensionless) for 45° elbow and 180° close return bends would be respectively around 180 and 300 45 and 75 5 and 10 300 and 500 180 and 300 45 and 75 5 and 10 300 and 500 ANSWER DOWNLOAD EXAMIANS APP

Process Equipment and Plant Design Pick out the wrong statement about the design of seive plate column and the bubble cap column. Weir height for a bubble cap plate column is the same as that for a seive plate column Weir length for a bubble cap plate is the same as that for the seive plate Weir height in case of a bubble cap plate ranges from 50 to 150 mm and is higher than the seive plate The downcomer design and the residence time in the downcomer is almost same for seive plate and bubble cap columns Weir height for a bubble cap plate column is the same as that for a seive plate column Weir length for a bubble cap plate is the same as that for the seive plate Weir height in case of a bubble cap plate ranges from 50 to 150 mm and is higher than the seive plate The downcomer design and the residence time in the downcomer is almost same for seive plate and bubble cap columns ANSWER DOWNLOAD EXAMIANS APP
